+/*
+HOW TO USE:
+
+ In exactly one translation unit (.c or .cpp file), #define MSF_GIF_IMPL before including the header, like so:
+
+ #define MSF_GIF_IMPL
+ #include "msf_gif.h"
+
+ Everywhere else, just include the header like normal.
+
+
+USAGE EXAMPLE:
+
+ int width = 480, height = 320, centisecondsPerFrame = 5, bitDepth = 16;
+ MsfGifState gifState = {};
+ msf_gif_begin(&gifState, width, height);
+ msf_gif_frame(&gifState, ..., centisecondsPerFrame, bitDepth, width * 4); //frame 1
+ msf_gif_frame(&gifState, ..., centisecondsPerFrame, bitDepth, width * 4); //frame 2
+ msf_gif_frame(&gifState, ..., centisecondsPerFrame, bitDepth, width * 4); //frame 3, etc...
+ MsfGifResult result = msf_gif_end(&gifState);
+ FILE * fp = fopen("MyGif.gif", "wb");
+ fwrite(result.data, result.dataSize, 1, fp);
+ fclose(fp);
+ msf_gif_free(result);
+
+Detailed function documentation can be found in the header section below.
+
+
+REPLACING MALLOC:
+
+ This library uses malloc+realloc+free internally for memory allocation.
+ To facilitate integration with custom memory allocators, these calls go through macros, which can be redefined.
+ The expected function signature equivalents of the macros are as follows:
+
+ void * MSF_GIF_MALLOC(void * context, size_t newSize)
+ void * MSF_GIF_REALLOC(void * context, void * oldMemory, size_t oldSize, size_t newSize)
+ void MSF_GIF_FREE(void * context, void * oldMemory, size_t oldSize)
+
+ If your allocator needs a context pointer, you can set the `customAllocatorContext` field of the MsfGifState struct
+ before calling msf_gif_begin(), and it will be passed to all subsequent allocator macro calls.
+
+See end of file for license information.

+# Small Deflate
+`sdefl` is a small bare bone lossless compression library in ANSI C (ISO C90)
+which implements the Deflate (RFC 1951) compressed data format specification standard.
+It is mainly tuned to get as much speed and compression ratio from as little code
+as needed to keep the implementation as concise as possible.
+
+## Features
+- Portable single header and source file duo written in ANSI C (ISO C90)
+- Dual license with either MIT or public domain
+- Small implementation
+ - Deflate: 525 LoC
+ - Inflate: 320 LoC
+- Webassembly:
+ - Deflate ~3.7 KB (~2.2KB compressed)
+ - Inflate ~3.6 KB (~2.2KB compressed)
+
+## Usage:
+This file behaves differently depending on what symbols you define
+before including it.
+
+Header-File mode:
+If you do not define `SDEFL_IMPLEMENTATION` before including this file, it
+will operate in header only mode. In this mode it declares all used structs
+and the API of the library without including the implementation of the library.
+
+Implementation mode:
+If you define `SDEFL_IMPLEMENTATION` before including this file, it will
+compile the implementation . Make sure that you only include
+this file implementation in *one* C or C++ file to prevent collisions.

+# Small Deflate
+`sdefl` is a small bare bone lossless compression library in ANSI C (ISO C90)
+which implements the Deflate (RFC 1951) compressed data format specification standard.
+It is mainly tuned to get as much speed and compression ratio from as little code
+as needed to keep the implementation as concise as possible.
+
+## Features
+- Portable single header and source file duo written in ANSI C (ISO C90)
+- Dual license with either MIT or public domain
+- Small implementation
+ - Deflate: 525 LoC
+ - Inflate: 320 LoC
+- Webassembly:
+ - Deflate ~3.7 KB (~2.2KB compressed)
+ - Inflate ~3.6 KB (~2.2KB compressed)
+
+## Usage:
+This file behaves differently depending on what symbols you define
+before including it.
+
+Header-File mode:
+If you do not define `SINFL_IMPLEMENTATION` before including this file, it
+will operate in header only mode. In this mode it declares all used structs
+and the API of the library without including the implementation of the library.
+
+Implementation mode:
+If you define `SINFL_IMPLEMENTATION` before including this file, it will
+compile the implementation. Make sure that you only include
+this file implementation in *one* C or C++ file to prevent collisions.
